Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603102, here are decompositions:

23 + 31603079 = 31603102
29 + 31603073 = 31603102
239 + 31602863 = 31603102
521 + 31602581 = 31603102
563 + 31602539 = 31603102
659 + 31602443 = 31603102
701 + 31602401 = 31603102
821 + 31602281 = 31603102

Showing the first eight; more decompositions exist.
